These are variant rotary vane engines implemented as 2 separate, axially coupled stages: an intake/compression stage & a combustion/expansion stage. The primary design objective is improved fuel efficiency. The engines are coupled to a starter motor which doubles as a dynamometer. Independent combustion & expansion ratios over 20:1 can be set to accommodate various fuels & for attaining the highest efficiency (currently ~10% & rising steadily as seals are improved). Wear surfaces & seals are graphite-on-steel whose miraculous lubricity & wear properties allow sustained operation without cooling or oil! Intake & exhaust profiles are smooth & practically continuous, reducing manifold effects & exhaust noise. Holding the vanes 'out' with solenoids provides an efficient means of throttling (by adjusting their duty cycle) since the rotors spin freely without any pumping losses. This makes it easy to gang stages & use them only when needed. Every power stroke (1 per revolution) occurs at maximum intake volume (no partial aspiration losses). I've been tinkering with ICEs for over 20 years in my spare time. These designs represent thousands of man-hours & a graveyard of previous prototypes. The program continues; 3 more models are currently on the drawing board. These ideas are offered with the hope that they may be inspirational & useful (or at least fun). Anyone interested is encouraged to build their own prototypes & to improve & apply these designs in any way that they see fit. -Dave

These are all very ... ( 8 months ago by RotaryICEman)

These are all very valid and popular questions. I get allot of complaints on the lack of other info. Yes, it's open source; I'm holding nothing back. There's no wiki, or drawings & my only defense is lack of time. I'm not retired, or independently wealthy, so progress is slow. However, this hasn't kept many determined individuals from making them using nothing more than the videos, my commentary & some Q&A. I hoped that some of them would help by sharing their work, but (continued)

(continued) this hasn't occurred yet. I'm currently working on Model 34. I've lost allot of time on fixtures, seal experiments & equipment modifications. I'll probably produce another video once I complete it, but it'll take a while. In the mean time, I may produce an interim video with construction tips, etc. There's more commentary in my channel & other vids.

When and where did ... ( 6 months ago by ioc55)

When and where did you get the engine from Robert Sullivan? WHich model do you have?

I read about the it ... ( 6 months ago by speedtroller)

I read about the it in an avaiation magazine in 1986. I was in Dallas in '98 and I called him. I drove to his shop in Sullivan OK and he showwed me everything. I went back a few days later with a video camera and we talked for a while and he gave me parts for a Rotary Vee. Some were protoype and I have one engine bank. He said it was enough to figure out how to build a Rotary Vee. I do not have a complete engine but I have video of a complete engine. I have video of it running from late 1980's.

The Sullivan Rotary ... ( 6 months ago by speedtroller)

The Sullivan Rotary Vee is in Synder, OK. Oh I also went to Chicago in the early 1990's and I saw the engine run in person. But the guy wouldn't let me take pictures. It was AWESOME. It was also displayed and run at the Oshkosh Air Show at some point in the late 80's early 90's. Now the marketing guy in Chicago won't let see it until I sign a letter of non-disclosure. But that meant that I could never talk about it again. So I said no and I didn't get to see what is happening with it now.

I personally know ... ( 6 months ago by ioc55)

I personally know Robert Sullivan. Can you tell me your name? I have alot of personal knowledge about this engine. I have a direct line to Robert Sullivan and can ask him anything I want at anytime.

I sent you a ... ( 6 months ago by speedtroller)

I sent you a message with my email address because I didn't want to post it on YouTube.
If you click on your account you should be able to read the message and we will talk through email instead of through posted comments. I hid all the parts that Robert Sullivan gave me and I am getting the video that I have on VHS and such put on DVD. See if you can find the message that I sent. If you know robert sullivan you know he had an airplane inside the shop area where the Rotary Vee parts are sitting

ioc55 - I think if you login and go to your account and then click on send message. Then you can click on General Messages - THere should be one from me in your General Messages. Try that and we'll talk.

I have known robert about 33 years and helped build the first engines there in snyder. I was there from the start

Yah well he is in prison. Do you own a ROTARY VEE? I didn't think so, I have one - actually I have two that run GREAT.

The powers that be should tell you to shut the heck up..... as they have to me and everybody else that knows about the Rotary Vee.

Look at the number ... ( 5 months ago by speedtroller)

Look at the number of parts - that is making me sick compared to the Rotary Vee concept. This may be viable but not usable - YOU find out for yourself.

actually I have about 30 of them
since he was my dad I have all of the prototypes he built

NOTICE: I finally started posting the sketches, pictures, schematics, source code, etc on the Yahoo! Group: 'Open_RotaryEngine'. I have hundreds of files to post, so it'll take me a while to finish it. Please read my commentary there BEFORE attempting to build your own engine, or before submitting any questions. Have fun. -Dave

i wonder have you ever tried to build a bigger prototype???....put it in a compact vehicle that grosses not more than 2800lbs!!!!....who knows.....you may become the new GM!!!!!XDXDXDXD

With my meager ... ( 1 month ago by RotaryICEman)

With my meager resources, I think that if I had attempted to build full scale models, I would still be working on Model 01. Even my small models take me about a year (in my spare time) to design, build & test. Sometimes after all that work on a new design, I discover that I attempted to violate a law of physics & I have to start over!

so with this new engine you are making a hit and miss type engine? sort of.....and keep up the good work! if you can could you post some more running videos?

(continued) Such ... ( 12 hours ago by RotaryICEman)

(continued) Such low losses during 'miss' cycles (including the absence of valvetrains, linkages, etc.) means that the engine could be efficiently coupled directly, in-line with an electric motor/generator/load assembly (next-gen Hybrid-Electric). Every power stroke could be requested on an individual basis, as needed & any number of extra stages (cylinders) can be added & used as needed; it's all about efficiency.
